Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1, FIG. 2 (A) (B), FIG. 3 (A)
2B, reference numeral 1 denotes an indoor unit main body of the air conditioner, 2 denotes a suction port provided on a front cover detachably mounted on the main body 1 and an upper surface of the main body 1, and 3 denotes an inside of the main body 1. A heat exchanger for exchanging heat with the air sucked in from the suction port 2; a blower fan 4 provided in an air passage for sending out the heat-exchanged air to an air outlet described later; This is the outlet for blowing out the exchanged air. Reference numeral 6 designates a rotatably supported bottom wall behind the outlet 5 and has a connecting portion at its front end or rear end, and the connecting portion is divided into a plurality by a plurality of connecting members (not shown). And a pair of left and right wind direction plates for adjusting the wind direction toward the left and right sides of the room. Reference numeral 7 denotes one or two upper and lower wind direction plates which are rotatably supported on both side walls in front of the left and right wind direction plate group 6 and adjust the wind direction toward the top and bottom of the room. . As shown in FIG. 2A, a first notch 7a is formed in the lower part of each of the left and right ends of the upper and lower wind direction plates 7 in a substantially arc shape so as to become narrower outward. It is. When the cooling operation is performed by providing the first all-notch portion 7a and forming it in a substantially arc shape so as to become narrower outwardly at the lower left and right ends of the upper and lower wind direction plates 7, FIG.
As shown by a solid arrow shown in FIG. 7A, the cool air blown out from the outlet 5 toward the left and right sides of the room is the first cutout.
7A, wind curtains are formed at both left and right ends of the vertical wind direction plate 7, whereby the surrounding room air indicated by thick arrows in FIG. 2A flows into the wind curtains. Therefore, no dew condensation occurs due to a temperature difference between the cool air sent from the outlet 5 and the room air, and no dew scatters. FIG. 7A shows a second embodiment as shown in FIG.
As shown in (B), there is a substantially straight portion formed in the lower part of the left and right ends of the upper and lower wind direction plates 7 so as to become narrower outward. As in the case of the first embodiment described with reference to FIG. 2A, the first notch 7a has a width narrower outward at the lower left and right ends of the upper and lower wind direction plates 7. When the cooling operation is performed, the cooling air blown out from the outlet 5 toward the left and right sides of the room when the cooling operation is performed, as shown by a solid arrow in FIG. All the air flows into the notch 7a, and wind curtains are formed on both left and right ends of the upper and lower wind direction plates 7.
(B), the surrounding room air indicated by the thick arrow does not flow into the curtain of the wind, and therefore, there is no dew condensation generated due to the temperature difference between the cool air sent from the outlet 5 and the room air. The dew scatter is also eliminated. In addition, the first notch 7a is formed in a substantially arc shape as in the first embodiment, or in a substantially linear shape as in the second embodiment, depending on design needs. It can be selected and adopted. As shown in FIG. 2 (A) as a first embodiment and FIG. 2 (B) as a second embodiment, the left and right wind direction plates 7b are divided into a plurality by the connecting member (not shown). A substantially arc-shaped second notch provided below the vertical wind direction plate 7 corresponding to the boundary position of the group 6. The second notch
7b is notched in a substantially arc shape, and at the same time, both ends thereof are formed in a substantially arc shape so as not to impair the design, and at the same time, both ends of the second notch portion 7b are expanded. Thus, the portion where dew condensation is most likely to adhere is cut out. Thereby, as shown in FIG. 2A as the first embodiment, and as shown in FIG. 2B as the second embodiment, the second notch 7b is connected to the connecting member (not shown). The left and right wind direction plate group 6 divided into a plurality
2 (A) and 2 (B), when the cooling operation is performed, the air blows from the air outlet 5 to the left and right of the room. The cold air sent to both sides flows into the second notch 7b to form a curtain of the wind.
(B), the surrounding room air indicated by the thick arrow does not flow into the curtain of the wind, and therefore, there is no dew condensation generated due to the temperature difference between the cool air sent from the outlet 5 and the room air. There is no dew scattering.

With the above configuration, a third embodiment shown in FIG.
As shown in FIG. 2A, two upper and lower wind direction plates including the first notch portion 7a and the second notch portion 7b described in the first embodiment based on FIG. 7 is provided in the air outlet 5, thereby preventing dew condensation and accompanying scattering of dew as described in the first embodiment.
An air conditioner that can more effectively adjust the vertical wind direction. Further, with the above configuration, a fourth embodiment shown in FIG.
As shown in FIG. 2B, the upper and lower wind direction plates provided with the first notch portion 7a and the second notch portion 7b described in the second embodiment with reference to FIG. 7 is provided at the outlet 5, thereby preventing dew condensation and the accompanying scattering of dew, as described in the second embodiment.
An air conditioner that can more effectively adjust the vertical wind direction.

With the above arrangement, as shown in FIG. 2A as the first embodiment, and as shown in FIG. 2B as the second embodiment, the air discharged from the outlet 5 during the cooling operation. Cold air flows into the first notch 7a and the second notch 7b to form a wind curtain, and room air does not flow into the wind curtain, thereby providing the air outlet 5 The air conditioner is capable of preventing the occurrence of dew condensation on the vertical wind direction plate 7 and the scattering of the dew accompanying the dew condensation, and adjusting the vertical wind direction by the vertical wind direction plate 7. Further, with the above configuration, a third embodiment is shown in FIG. 3A, and a fourth embodiment is shown in FIG.
As shown in (B), at the time of the cooling operation, the cool air sent out from the outlet 5 flows to the first notch 7a and the second notch 7b to form a wind curtain. This prevents indoor air from flowing into the inside, thereby preventing the occurrence of dew condensation on the upper and lower two wind direction plates 7 provided at the outlet 5 and the scattering of the dew accompanying the dew condensation. An air conditioner that can more effectively adjust the vertical wind direction.

[0009]

As described above, according to the present invention, it is possible to prevent condensation from adhering to the upper and lower wind direction plates provided at the air outlet during the cooling operation, and to form a substantially circular arc on both sides according to the need for design. An air conditioner that can select and adopt a vertical wind direction plate having a cutout formed in a substantially straight line.
